Jillian Michaels' Ripped in 30/6 week 6 pack

Man today I felt like I haven't lost any weight, I went shopping for jeans and when I tried one my size it didn't fit, I had to search a bigger size so...I haven't lost any weight or what the fudge??

So I kinda finished Ripped in 30 and I don't see changes whatsoever, instead I feel like I gained weight. I feel frustrated and my abs, no change at all...
